1999 navigator I have a factory installed anti theft system. I purchased an alarm switch that works, however, the system is a DEI self starter, which my alarm switch does not support. Aside from the expensive dealer, is there a place to obtain a keyless starter switch.

I know this worked with my 99 navigator 32 valve used a viper car starter.

Is the security light flashing while trying to start the vehicle ?
The theft warning system provides the vehicle with protection from unauthorized entry into the passenger compartment and engine compartment (hood opening). It also protects against engine starting through ignition keylock cylinder tampering. If triggered, the system provides both audio and visual alarm signals and disables the starter circuit.
Sorry but you will have to take it to the dealer if it's the anti-theft system

If it is an aftermarket alarm system it is tied into your starter circuit coming off of your ignition switch. You need to remove plastic covers under steering wheel on toyota vehicles it is phillips head screws and some 10mm bolts. Find alarm system this is tricky but possible find the wire that is tapped into a thick wire leading up to steering column to the key ignition switch it should be a thicker wire sometimes red in color that wire is the starter interupt for the alarm system remove that wire (cut it) at alarm side and starter function should be restored.
IF IT IS AN AFTERMARKET SYSTEM hope this helps

Your problem is your BCM or known as body control module is looping into theft mode and in return not getting power to the starter so I'd check with ford on a BCM flash to factory default settings hope this helps you

This is most likely caused by the car's anti-theft system. Most newer cards require a separate module to be installed to override the anti-theft system while the remote start is in use. Otherwise, when the anti-theft system detects an anomaly, it will immobilize the vehicle.
DEI makes a 556H module for this purpose. The link shows the instrall manual for this device.

Starting System
The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
------------------------------------------------------------------------------
The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed. System Arming
The system will be armed by the remote entry transmitter when the following input sequence is followed:

Turn the ignition switch off and remove the key.

Close all doors (unlocked).

Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.

Wait for the anti - theft warning lamp to turn off.

The system will also be armed when the following input sequence is followed:

Turn the ignition switch off and remove the key.

Open a door. Alarm warning lamp will flash.

Lock doors with power door switches. Alarm warning lamp will now glow steadily.

Close all doors.

Wait for the anti - theft warning lamp to turn off.

Opening any door will activate the alarm after the alarm is armed. Disarming an Untriggered System
The system can be disarmed by performing one of the following procedures.

Driver or RH front door is unlocked with a key.

Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.

If remaining in the vehicle, turn the ignition switch to ON or ACC position.

System Triggering
The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first. Disarming a Triggered System
Carry out either of the following steps will disarm the triggered alarm system.

Driver or RH front door is unlocked with a key.

Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.

Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
--------------------------------------------------------------------Passive Anti-Theft System (PATS)
The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
The PATS functionality is incorporated within the powertrain control module.
PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized. Anti-Theft Indicator
Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

you can remove the ignition switch (the electrical part) from the ignition lock (the key and lock part} and put a screwdriver in the switch part, and turn it like it was the key. as far as the anti theft part goes it may be an aftermarket alarm system installed on the starter circuit.
if that is the case it usually only keeps it from turning over not running.
so you may be able to just bypass a relay,
Look for a wire that someone cut in half up by the switch, and attached there own wire to both ends. just remove there wires and reattach, or temperarily jumper the factory wire back together. see if it turns over.

The ignition lock anti-theft switch (19A438) detects if the ignition key cylinder is broken or "slam pulled" during a theft. The ignition lock anti-theft switch is always monitored by the remote anti-theft personality (RAP) module. This allows the alarm system to be triggered in the case that the ignition lock anti-theft switch detects tampering of the ignition key cylinder (even in the event that the alarm is not active at the time).
Refer to the Section 501-14B for more details on the keyless entry remote transmitter (15K601).
The door open warning lamp switch (14018) communicates to the RAP module through the generic electronic module (GEM). This input to the RAP will cause the anti-theft alarm to be sounded if the anti-theft alarm was armed.
The door disarm switches are assembled into both LH and RH lock sets. The door disarm switch must be triggered before the mechanical lock unlocks. This is to prevent the anti-theft alarm from activating when it should have been disarmed.
The RAP module controls the anti-theft system and is the brains of the keyless entry system. The RAP module communicates with the GEM to request that the interior lights be turned ON/OFF with use of the keyless entry remote transmitter, and the GEM communicates to the RAP to inform when the door is opened. Refer to Section 418-00 for inter-module communication.
The RAP module has three wire connectors attached to it:

The antenna for the keyless entry remote transmitter.

26 circuit connector (C256).

22 circuit connector (C257).

In addition to the perimeter alarm that uses the door open warning lamp switch, the RAP module also uses the ignition lock anti-theft switch and the autolock/relock feature to prevent theft of the vehicle. For a full description of the autolock/relock system, refer to Section 501-14B .
The THEFT LED is found on the instrument panel between the tachometer scale and the needle pivot point. The LED is illuminated during prearming and flashes when armed or triggered. Prearming and Arming the System
The system can be armed if:

The ignition is OFF.

The PANIC alarm is OFF.

All doors are closed.

There are two ways to prearm the system:

Press the LOCK button on the transmitter.

Open a door, press the power door lock button and close the door.

After 30 seconds the system will be armed and the theft indicator in the cluster will flash every two seconds. Disarming an Untriggered System
An armed system will be disarmed with one of these valid actions:

Pressing the UNLOCK button on the transmitter.

Placing a key in the door and turning to UNLOCK.

Turning the key to RUN or ACC.

The anti-theft alarm can be triggered by the following conditions:

The ignition cylinder is damaged with or without the RAP being armed.

A door is opened without disarming the armed RAP module.

The remote transmitter can activate a panic alarm which is similar to an anti-theft alarm, but does not deactivate the starter or cause the theft indicator to flash. Disarming a Triggered System
If the system has been triggered, (the horn honks, the lights flash, and an external starter interrupt relay is engaged), the system can be disarmed by:

Pressing the UNLOCK or PANIC button on the transmitter.

Putting a key in the door and unlocking the door.

Turning the ignition to RUN/ACC (Turning the key to RUN/ACC will not disarm an alarm that has been triggered by the ignition lock anti-theft switch.).

Section 13-11: Anti-Theft System, Active
1998 Windstar Workshop Manual
DESCRIPTION AND OPERATION
Anti-Theft Alarm System
NOTE: The system immediately monitors the ignition key lock cylinder upon removal of the key from the ignition. It is not necessary to arm the system for ignition key lock monitoring.

The anti-theft alarm system:

protects the vehicle from unauthorized entry into the passenger compartment, engine compartment and cargo area.

monitors the status of the ignition key lock cylinder.

is controlled by a remote anti-theft personality (RAP) module. The remote anti-theft personality module also controls the electronic door lock functions. Refer to Section 01-14B for more details.

when armed, detects unauthorized entry into the passenger compartment by using an input from the GEM module regarding the state of the door or liftgate (open or closed).

protects the engine compartment with a hood switch which is located on the LH cowl vent panel and is part of windshield wiper motor wiring (17A477) .

triggers an alarm if the ignition lock cylinder is forcibly removed from the steering column.

The remote anti-theft personality module is located behind the instrument panel (04320).

It contains a radio receiver that receives the RF signal from the keyless entry remote transmitter (15K601) through the alarm and lock system antenna (15603) and sends the appropriate command to the power door locks, the horn relay, or the generic electronic module.

The remote anti-theft personality module is equipped with an internal backup power supply which holds the programmed code in memory in the event the vehicle battery is disconnected.

The remote entry PANIC button will disarm the anti-theft system only when the perimeter alarm is triggered and sounding.

------------------------------------------------
System Triggering
NOTE: Although the remote entry PANIC alarm is not associated with the monitoring of the vehicle, the user will frequently say that the theft system was triggered when actually the keyless entry remote transmitter PANIC button was inadvertently pressed. A panic alarm will not flash the THEFT indicator.

The alarm can be triggered by the following events if the system has been armed and has not been disarmed first:

Open any door or liftgate.

Open the hood (16612) (if the hood was open when the system was armed, it must be closed before it can trigger the alarm).

Dislodge the ignition key lock cylinder.

The anti-theft system may be triggered inadvertently when the module is disconnected and then reconnected. To avoid inadvertent alarm triggering, disconnect the smaller 22-way connector first.

When the system is triggered the perimeter alarm will operate as follows:
The remote anti-theft personality module will pulse the following outputs at approximately 1.3 Hz, 50 percent duty cycle for two minutes 45 seconds for North America.
NOTE: Other perimeter alarms can be programmed for the system.

low beam headlamps

parking lamps

horn

THEFT indicator

The perimeter alarm can be retriggered, after a perimeter alarm has sounded for 165 seconds. After a perimeter alarm has timed out, if any trigger input is first seen as normal and is then seen in its trigger state, the perimeter alarm will be retriggered. The perimeter alarm can be triggered a total of three times between an arming sequence and a disarm event. An active panic alarm will be deactivated when a perimeter alarm is triggered (a perimeter alarm overrides a panic alarm).

You might have a problem with the antitheft system, I don't know what you've done or tested so far. But usually with the alarm enabled there wont be any start at all. It does sound like there is a problem with the ignition switch, but that's only if it starts and stalls after you let the ignition key go. The anti-theft alarm, is this a VTD, factory system, a factory alarm system, or an aftermarket alarm?
